What will be the difference in mass number if the number of neutrons halved and the number of electrons doubled in `._(6)^(12)C`

Text Solution

Verified by Experts

Mass no is the sum of protons
If `""_(6)^(12) C to "Initial" to "final"`
`{:("protons:",6,-6),("Neutrons:",6,-3),("mass no",12,-9):}`
Hence the decrease in mass no is 25%
